It's somewhat obvious that you don't know what's on the vendors, based on how you talk. You say the items on the VIP vendor were obviously taken from the CE vendor. The problem is there aren't items. There's an item. One. A 1,500,000 credit speeder. That's all. Furthermore, yes, it's entirely possible for it to have been thrown on there at the last minute. I guarantee you they have plenty of extra speeder models, because over time they've made and tried various different ones. In games like these, for every model that gets used there's plenty of extras. All they had to do was take one they had made but not used yet and throw it in there.
I have to wonder if you've even been to the VIP area. I personally don't care if people can buy access to it or not, because it's a little platform above the main bar. It has two vendors, and a bartender in it. It existing and being exclusive didn't serve any real purpose, aside from housing the vendor, which it still does just fine. The "normal folk" won't be able to buy from him, just the same, so you don't need to worry.
